## Транскрипт

### Intro []

have you ever tried transcribing a podcast meeting recording or interview and found yourself wondering who said what that's exactly the problem that speaker diarization solves it's like giving your transcription a brain that can tell one speaker from another speaker diarization is the process of breaking an audio file into segments based on who is speaking this technology is a game Cher for creating organized and speaker labeled transcripts which are essential for so many Industries and applications whether you're working with business calls interviews or media production understanding who said what is critical speaker diarization makes your audio data more structured searchable and actionable saving hours of manual effort and adding immense value to your workflows in this video I'll walk you through how to use assembly AI API in Java to implement speaker diarization step by step the

### Creating an AssemblyAI API Key [1:00]

first thing you want to do is get your free API key from assembly AI in order to do that click on the link in the description box below and once you're on this page head on over to get started at this point you can create your account for free and you get $50 in free credits to start using assembly AI API and the speaker diarization model is included in this once you have logged into assembly AI dashboard you should see something like this on the right side is where your API key is and you can easily copy your API key and paste it in whatever ID that you're using on the left side you get to see all of these code examples that you can easily run you also get to choose your language of preference since we're doing this in Java you can click the Java SDK to get that respective code to run our code I'm

### Installing AssemblyAI's Java SDK [1:49]

going to be creating an empty project in intell J and I'm going to click create next we want to install the latest version of assembly AIS Java SDK in our project dependencies so we want to paste this right into our build. gradle file also make sure to change this value right here to assembly ai's latest Java SDK version to find out that value you can click on assembly I Java SDK link right here on the documentation page and that will take you to the maven Central repository website where you will be able to see what the latest value of our Java SDK version is in this case it is 4. 0. 0 you can also copy directly from here so click copy to clipboard back in our Java app in build. gradle under dependencies I'm going to be pasting that line of implementation code and I'm going to be running this next we can go onto our main. Java

### Speaker Diarization in Java [3:00]

file and start writing our code the first thing we want to do is import assembly Ai and we also want to import transcripts we then want to go ahead and create an assembly AI client object which will be communicating with the API and sending our request over and also getting the results back at this point this is where you want to paste your API key and call the bill function next we need to create a config object which will contain our transcript parameters so in our case we want to turn on speaker labels to do this we will be calling the transcript optional params object and we'll set speaker labels to True next we want to define a URL of an audio or video file that we would like to transcribe one that preferably has multiple speakers in it now we will send both our audio URL as well as our parameters to assembly Ai and store the returning transcript into a transcript object lastly we will format the way that we want to print this out let's go ahead and run

### Demo [5:45]

this and this is the output that you should be getting from assembly AI a transcript which contains all the speakers involved in this audio file as well as what they have said if you would like to transcribe a file which is stored locally you can make use of this line of code right here and also to improve the accuracy of the diarization model you can also set speakers expected equals to the number of speakers in your audio file or video file and this will actually improve the performance of the speaker diarization model because it knows how many speakers to expect to learn to build more with assembly AI check out our documentation page for a list of all our endpoints as well as all the amazing tutorials that we have on our YouTube channel
